Progression of Spanish National Team Basketball Players by Age and Sex

The aim of this study was to analyze the relationship between basketball players that have participated in the Spanish national team at different age categories and their progression through these categories. This progress is differentiated according to sex. The data for this study contain information about 320 players (163 females and 157 males). Results show that only a small percentage of players recognized as talented young players reached athletic excellence when adults. The evolution of the level of participation for females and males was similar. There was a break in the continuity of participation when comparing under-16 and senior categories. This rupture is also observed in female players in the move from under-18 to senior categories.

EFECTO DE UN PROGRAMA DE ACTIVIDAD FÍSICA DE MODERADA A VIGOROSA DE DIEZ MESES SOBRE EL VO2MÁX Y EL PORCENTAJE DE GRASA CORPORAL EN NIÑOS CON SOBREPESO Y OBESIDAD

Objetivo: Evaluar el efecto de un programa de actividad fisica con intensidad de moderada a vigorosa bajo el modelo CATCH sobre el porcentaje de grasa corporal y capacidad aerobica en ninos con sobrepeso u obesidad. Metodo: Veintiseis ninos (15 hombres y 11 mujeres) (edad = 9.4 ± 0.3 anos), diagnosticados con sobrepeso u obesidad por su indice de masa corporal, participaron en un programa de actividad fisica con intensidad moderada a vigorosa bajo el modelo de CATCH, 2 veces por semana por un periodo de 10 meses. El programa estuvo compuesto por ejercicios de intensidad moderada a vigorosa (56 %) y fue evaluado por el sistema para observar el tiempo de instruccion de actividad fisica (SOFIT). Antes y despues del programa se evaluo el porcentaje de grasa corporal con la ecuacion de Slaughter et al. (1988), valorando los pliegues cutaneos de triceps y pantorrilla. La capacidad aerobica se evaluo con el test Course Navette de 20 metros calculando el consumo maximo de oxigeno (VO2max) por la ecuacion de Leguer et al. (1984). Resultados: Se encontro una reduccion significativa en el porcentaje de grasa corporal (Δ% = -2.4, p = 0.022) y un aumento significativo en el VO2max (Δ% = 11.3, p ≤ 0.001). Conclusion: La actividad fisica con intensidad de moderada a vigorosa bajo el modelo de CATCH fue capaz de mejorar la capacidad aerobica y reducir el porcentaje de grasa corporal en ninos con sobrepeso u obesidad.

Conceptions of ability and self-determined motivation in young Spanish athletes

This investigation examined the relationship between implicit ability beliefs and self-determined motivation. The sample was comprised of 775 young athletes between the ages of 12 and 17 competing at national level in Spain. The participants completed the Spanish version of the Conceptions of the Nature of Athletic Ability Questionnaire (CNAAQ-2) and the Sport Motivation Scale (SMS). The results revealed a positive and significant correlation between stable ability beliefs and learning ability, and between self-determined motivation and perceived sports ability. To the contrary, stable entity beliefs were negatively correlated with self-determined motivation. Competitiveness in sports was significantly predicted by self-determined motivation, and the latter, in its turn, was positively predicted by learning belief and negatively by stable entity beliefs.

Reflexiones acerca de la iniciación al baloncesto a través de la enseñanza de las reglas

Traditionally, the process of teaching and learning has come from the election, by the coach, of those technical and tactical contents considered appropriate depending on the category, and from this point on, has turned all the planning, leaving out the teaching of the rules to an occasional appearance, without a prior organization in most of the cases. If we consider that the rules of game are a key element for the game, we could start to help the player to learn the technical and tactical means from the knowledge of the rules of game. With this study, we try to understand the current state of regulations in the stage of Minibasket and understand what is the role of rules in the introduction to basketball and how to sequence the teaching and learning of technical and tactical means from the rules.
